JP 2001-158585 A

  The technique disclosed in Patent Document 1 is a countermeasure against the passenger conveyor device, and is based on the premise that the building in which the passenger conveyor device is installed has an earthquake-resistant structure. Therefore, even if measures are taken against the fall of the passenger conveyor device during an earthquake, it is meaningless if the building is damaged by shaking.

  The objective of this invention is providing the passenger conveyor apparatus for building earthquake resistance which can improve the earthquake resistance with respect to a building.

  In order to achieve the above object, the present invention provides a pit in which the upper end of a passenger conveyor frame is fixed to a strength member provided in a building via a connecting means, and the lower end of the frame is formed on the ground. It was fixed through fixing means.

  As described above, the upper end of the passenger conveyor frame is fixed to the building, and the lower end is fixed to the ground, so that the passenger conveyor is suppressed against shaking during an earthquake of the building. As a result, it is possible to obtain a passenger conveyor device for building earthquake resistance that can improve the earthquake resistance of the building.

  A first embodiment of a passenger conveyor device for building earthquake resistance according to the present invention will be described below with reference to an escalator device shown in FIGS. The escalator device 1 shown here is installed across a platform (ground) 2 of a station building and a bridge passage (building) 4 supported from the platform 2 via a support 3.

  And the escalator apparatus 1 has installed the frame 5 across the floor surface 2F of the platform 2 which is the ground, and the floor surface 4F of the bridge passage 4 which is a building.

  As shown in FIG. 5, the frame 5 includes a pair of left and right side frames 6A and 6B and a connecting beam 7 that connects the side frames 6A and 6B. The side frames 6A and 6B include upper chord members 8A and 8B extending in the longitudinal direction, lower chord members 9A and 9B disposed below the upper chord members 8A and 8B, and the upper chord members 8A and 8B. 8B and lower chord members 9A and 9B are provided with connecting members 10A and 10B.

  As shown in FIG. 4, the frame 5 configured in this manner includes an inclined section L1, an upper horizontal section L2 continuous with the upper end of the inclined section L1, and a lower horizontal section L3 continuous with the lower end of the inclined section L1. And have.

  The lower horizontal section L3 of the frame body 5 thus configured is housed in the pit 2P provided in the home 2, and its end is engaged in the vicinity of the floor surface 2F, and the end of the upper horizontal section L2 Is engaged in the vicinity of the floor surface 4F of the bridge passage 4. In such a frame body 5, a plurality of step plates 11 connected endlessly are guided so as to be rotated by a driving means (not shown). A balustrade panel 12 is erected on each of the side frames 6A and 6B along both sides of the tread board 11, and a moving handrail 13 driven in synchronization with the tread board 11 is guided along the periphery of the balustrade panel 12. Has been.

  The upper end of the frame body 5 configured as described above, specifically, the upper end portion of the inclined section L1 of the frame body 5 is connected to the support body 3 of the bridge passage 4 which is a strength member as a wire rope as a connecting means. 16 are connected. Specifically, the connecting seat 17 is fixed across the upper ends of the left and right lower chord members 9A and 9B in the inclined section L1 of the frame body 5, and the eyebolts 18A and 18B are connected to the connecting seat 17 and the support body 3, respectively. A tension is applied through the wire rope 16 between the eyebolts 18A and 18B. In place of the wire rope 16, a chain or a connecting rod may be used.

  Furthermore, the lower portion of the frame 5, specifically, the portion housed in the pit 2 </ b> P provided in the home 2 at the lower end of the inclined section L <b> 1 of the frame 5 is fixed to the fixture 19. More specifically, as shown in FIG. 3, a fixture 19 having a mounting surface 19S having the same inclination as the inclined section L1 of the frame 5 is fixed in the pit 2P, and the frame 5 facing the mounting surface 19S is fixed. A fixed seat 20 is provided at the lower end of the inclined section L1, and the fixed seat 20 and the mounting surface 19S are fixed by a known fixing means 21 such as a bolt, a nut, or welding.

  As described above, the upper end of the frame 5 of the escalator device 1 is connected to the support 3 via the connecting means (16, 18A, 18B), and the lower end of the frame 5 is connected to the home via the fixing means 21. By fixing to 2, even if the bridge passage 4 tries to sway during an earthquake, the swaying is suppressed by the frame 5 of the escalator device 1 being a strength member. As a result, the earthquake resistance of the bridge passage 4 is improved.

  By the way, in the above-described embodiment, the escalator device 1 withstands the shaking of the building (bridge passage 4) to some extent by the escalator device 1 when the seismic intensity is low. By doing so, a large force acts on the frame body 5 of the escalator device 1 and tries to deform the frame body 5.

  As described above, when a large force is expected to act on the frame 5 of the escalator device 1, the frame 5 is reinforced as shown in the first modification of FIGS. 6 and 7. That's fine. The same reference numerals as those in FIGS. 1 to 5 indicate the same components, and thus detailed description thereof is omitted.

  That is, the upper bent portion P1 and the lower bent portion P2 of the frame body 5 where compressive force and tensile force tend to concentrate due to the shaking of the building (bridge passage 4) are extended from the upper horizontal section L2 to a part of the inclined section L1. The reinforcing plates 22A and 22B are provided, and the lower reinforcing plates 23A and 23B are provided from the lower horizontal section L3 to a part of the inclined section L1.

  The upper reinforcing plates 22A and 22B and the lower reinforcing plates 23A and 23B exceed the width dimension W of the side frames 6A and 6B, which causes a problem in the installation of the components of the escalator device 1. As shown in FIG. 4, plate materials having substantially the same thickness as the upper chord members 8A, 8B and the lower chord members 9A, 9B are used so as to be positioned within the width dimension W of the upper chord members 8A, 8B and the lower chord members 9A, 9B.

  The upper reinforcing plates 22A and 22B and the lower reinforcing plates 23A and 23B extend in the height direction and are connected by welding over the lower edges of the upper chord members 8A and 8B and the upper edges of the lower chord members 9A and 9B. In addition, it is connected to the connecting members 10A and 10B by welding as necessary.

  In this way, by reinforcing the upper bent portion P1 and the lower bent portion P2 of the frame body 5, even if the bridge passage 4 is about to roll due to an earthquake, the upper bent portion is bent against the bending due to the compressive force or tensile force. P1 and the lower bent portion P2 are not deformed. As a result, the rolling of the bridge passage 4 can be prevented by the frame 5 of the escalator device 1, and the earthquake resistance of the bridge passage 4 can be improved. In other words, since the escalator device 1 improves the earthquake resistance of the bridge passage 4, the support body 3 of the bridge passage 4 has only to be designed with emphasis on the vertical load. Therefore, the design and construction of the support body 3 can be simplified. It becomes possible to.

  Furthermore, without connecting and fixing the upper horizontal section L2 and the lower horizontal section L3 of the frame 5 to the bridge passage 4 that is a building, the upper and lower ends of the inclined section L1 of the frame 5 are the bridge passage 4 that is a building. By directly connecting and fixing to the support body 3 and the home 2, the upper horizontal section L 2 and the lower horizontal section L 3 are not affected by the compressive force or tensile force due to the rolling of the bridge passage 4. Large bending stress does not act on the upper bent portion P1 and the lower bent portion P2 of the frame 5. As a result, the mechanical strength of the upper reinforcing plates 22A and 22B can be lowered or omitted depending on circumstances.

  8 and 9 show a second modification of the frame body 5, which is a reinforcing configuration for connecting and fixing the upper and lower ends of the frame body 5 to the bridge passage 4 and the platform 2, and FIG. The same reference numerals as those shown in FIG. 7 indicate the same components, and thus detailed description thereof is omitted.

  In the second modification, the configuration different from that of the first embodiment is that portions other than those reinforced by the upper reinforcing plates 22A and 22B and the lower reinforcing plates 23A and 23B in the inclined sections L1 of the side frames 6A and 6B, respectively. It is further reinforced to improve the earthquake resistance of the building.

  That is, in the side frames 6A and 6B of the inclined section L1 other than those reinforced by the upper reinforcing plates 22A and 22B and the lower reinforcing plates 23A and 23B, the lower and upper edges of the upper chord members 8A and 8B and the lower chord members 9A and 9B. In addition, the upper edge side intermediate reinforcing plates 24A and 24B and the lower edge side intermediate reinforcing plates 25A and 25B are connected in the same manner as the upper reinforcing plates 22A and 22B and the lower reinforcing plates 23A and 23B.

  In this way, by connecting the upper edge side intermediate reinforcing plates 24A, 24B and the lower edge side intermediate reinforcing plates 25A, 25B to the lower and upper edges of the upper chord members 8A, 8B and the lower chord members 9A, 9B, the upper chord member 8A, As a result, the cross-sectional areas of 8B and the lower chord members 9A and 9B are increased.

  As a result, it is possible to improve the strength of the upper chord members 8A and 8B and the lower chord members 9A and 9B in the inclined section L1, and the upper bent portion P1 and the lower bent portion P2 also have the upper reinforcing plates 22A and 22B and the lower portions. Since it can reinforce with the reinforcing plates 23A and 23B, it is possible to obtain the frame 5 that is more resistant to compressive force and tensile force, and to further improve the earthquake resistance of the building (bridge passage 4).

  FIG. 10 shows a third modification of the frame 5 that is a further modification of FIG. 8 and FIG. 9, and the same reference numerals as those shown in FIGS. Description is omitted.

  In the third modified example, as a configuration for further improving the strength against the compressive force of the upper bent portion P1 of the frame 5, the lower chord members 9A and 9B and the inclined section L1 in the upper horizontal section L2 are provided inside the upper bent section P1. A reinforcing beam 26 is provided to straddle the lower chord members 9A and 9B, and the auxiliary beam 27 is closed between the reinforcing beam 26 and the lower chord members 9A and 9B, or the upper reinforcing plates 22A and 22B are extended to the reinforcing beam 26. It extends so as to close the space between the reinforcing beam 26 and the lower chord members 9A and 9B.

  Thus, by providing the reinforcing beam 26, even if the compressive force acts on the frame 5 and the upper bent portion P1 is bent inward, the reinforcing beam 26, the auxiliary reinforcing plate 27, and the upper reinforcing plates 22A and 22B. Therefore, the bending can be counteracted, and as a result, the strength of the frame 5 can be improved and the shaking of the building can be suppressed.

  FIG. 11 shows a second embodiment of a passenger conveyor device for building earthquake resistance according to the present invention. The same reference numerals as those shown in FIG. 1 to FIG. Description is omitted.

  In the present embodiment, a connecting seat 28 is provided across the pair of left and right side frames 6A and 6B at the end of the upper horizontal section L2 of the frame 5, and the connecting seat 28 and the strength beam 29 of the bridge passage 4 are provided. Eyebolts 18A and 18B are provided respectively, and the eyebolts 18A and 18B are connected by a connector 30.

  That is, in the first embodiment, the lower portion of the upper end portion in the inclined section L1 of the frame body 5 and the support body 3 are connected by the wire rope 16, but in the second embodiment, The end portion of the upper horizontal section L2 of the frame 5 and the strength beam 29 of the bridge passage 4 that is a strength member are connected by a connecting tool 30, and the same effect as that of the first embodiment is achieved. Can do.

  In the second embodiment, the upper reinforcement plates 22A and 22B, the lower reinforcement plates 23A and 23B, the upper edge side intermediate reinforcement plates 24A and 24B, and the lower edge side intermediate are also attached to the frame 5 according to the scale of the building. The reinforcing plates 25A and 25B, the reinforcing beam 26, and the auxiliary reinforcing plate 27 can all be provided or selectively provided.

  FIG. 12 shows a fourth modification of the frame 5 that is a further modification of the third modification of FIG. 10, and the same reference numerals as those shown in FIGS. 1 to 11 indicate the same components. Detailed description is omitted.

  In the present embodiment, the configuration different from the third modification is that instead of providing a lower reinforcing plate in the lower bent portion P2, upper edge side intermediate reinforcing plates 19A and 19B and a lower edge side intermediate reinforcing plate 20A provided in the inclined section L1. , 20B are provided to extend to the end of the lower horizontal section L3.

  However, in this modification, it is a premise that the lower end portion of the frame 5 is fixed in the pit 2P at the lower end of the inclined section L1. That is, the fact that the lower end of the frame 5 is fixed in the pit 2P at the lower end of the inclined section L1 means that even if a compressive force and a tensile force are applied in the longitudinal direction of the frame 5, A force that deforms the lower bent portion P2 is not applied to the lower bent portion P2 at the boundary with the horizontal section L3. Therefore, it is not necessary to install a large lower reinforcing plate that is heavy in weight. This is because the upper edge side intermediate reinforcing plates 19A and 19B and the lower edge side intermediate reinforcing plates 20A and 20B can sufficiently cope with each other.

  However, in each embodiment, when the lower horizontal section L3 of the frame 5 is fixed to the ground, a force that deforms the lower bent portion P2 acts, so that it is necessary to install a lower reinforcing plate.

  Also according to the present embodiment, substantially the same effects as those of the above-described embodiments can be obtained.

  As described above, according to the present invention, the upper end portion of the frame body 5 of the escalator device 1 is connected to the support body 3 and the strength beam 29 that are strength members of the bridge passage 4 that is a building, and then the frame body. By fixing the lower end of 5 to the ground (home 2), as a result, the bridge passage (building) 4 is supported by the frame 5 of the escalator device 1, and the earthquake resistance of the bridge passage 4 is improved. can do.

  By the way, although each said embodiment demonstrated the escalator apparatus as a passenger conveyor apparatus, it is not specified to an escalator apparatus, It can apply also to the electric road installed in an inclination.
